What is the minimum Tests Required for Statement Coverage and Branch Coverage?

• Statement coverage is 2, Branch Coverage is 2

• Statement coverage is 3 and branch coverage is 2

• Statement coverage is 1 and branch coverage is 2

• Statement Coverage is 4 and Branch coverage is 2

Error guessing ..

• supplements formal test design techniques

• can only be used in component, integration and system testing

• is only performed in user acceptance testing

• is not repeatable and should not be used

Consider the following statements:

i. 100% statement coverage guarantees 100% branch coverage.

ii. 100% branch coverage guarantees 100% statement coverage.

iii. 100% branch coverage guarantees 100% decision coverage.

iv. 100% decision coverage guarantees 100% branch coverage.

v. 100% statement coverage guarantees 100% decision coverage.

• ii is True; i, iii, iv & v are False

• i & v are True; ii, iii & iv are False

• ii & iii are True; i, iv & v are False

• ii, iii & iv are True; i & v are False
